I'll pick up where Narguille left off, cause I'm almost in the exact same situation.
I'm left handed and play right handed. I'm not sure if being left handed is the cause, but I do know that I've favored legato styles with lots of hammer-on & pull-off's to get my speed up. I've been playing many years and have gotten by ok with rather poor right handed technique, but I've recently decided that to smooth out my playing, I've got to get better at picking.
Since I've found GMC, I have bookmarked several ap lessons and exercises and have improved somewhat in about two months since I started working hard at it. I'm practicing about two hours a day now. What I've found is that I can play accurately and cleanly up to a point, but once I get past my speed barrier (which is a rather lame 90 bps on most exercises), my hand and arm tenses up and just quits working.
Way back in college (believe me, that was a long time ago now) I had a friend who could play very fast. He had been playing for about the same number of years as I, but still had what I thought was unbelieveable speed. Based on that, I've come to the conclusion that there limits on how fast I will ever be.
Now that I am practicing more seriously though, I'm hoping to achieve new thresholds. The cool thing is that my left hand has no problem with any of the excersies at the speeds my right hand begins to break up so I think that I can focus on my right hand technique and improve my abilities tremendously.
One question that does come to mind is, How rapidly should I hope to achieve speed gains? When you look back in time Muris, did you find that your right hand picking reached a certain point very quickly or instead, did you observe speed improvements very slowly? For example, do you recall if in the early days of your practicing you had set certain goals of 100, 110, 120, 130 ... and did you have to work hard at each level to reach them?
That's what I've done for the short term. I've set a goal of 110 (versus my current 90) for most exercises in one years time. If I can achieve that, I want to keep working towards new goals, but if I've got some build in limit, I really would rather focus on something other than speed. I.e., developing my style and composition skills.
For now, keep the ap exercises and lessons coming and put plenty of backing tracks in for 90, 95, 100, & 105 speeds! :-)
Not sure how many times you've received this request, but if you still have the midi files, can you add a 95 bps speed to some of your existing lessons? ...like ap 3rds, rocking tune intermediate, & other ap lessons?
As always, I'm really grateful for this site and the world class contributors here. It's inspirational to parctice here and I'm seeing measurable gains in versatility & technique already in the two short months that I've been hanging around.
